And a great service to the listening community!
Even I'm surprised by my ability to find value...(compassion for a different purpose?) but that's mostly my issue! As usual, some crap annoyed me, and it doesn't now...
I need to get over myself!
Still the psuedo memory of having been there and having an audience tape of the show for years makes my affection for the show, playing and quirks of the recording demand that I raise the score!! grade, rating, whatever... Still at least a four in my mind, but I am probably more generous because of the experience!

During the previous Red Rocks booking, in '79, McNichols Arena was rented and set up as an alternate venue. Though tix said "If Rainout: McNichols", it was unavailable (or too expensive) this time, so the band played in a downpour. This was not the local showers spinning off the foothills, but a Four Corners monsoonal flow that crossed the Rockies. It rained all three nights but this night had streams running down the side of the seating area and crew using squeegees on the stage. A crowd of thousands, all hiding under plastic. The PA suffers and at times the band does too, making this the lesser of the three nights (the next night is much better). It got cold and people trickled out steadily. I remember in '85 & '87 people would say "remember the rainy year? Was that '82 or '83?" with survival-fondness. It would seem Jer just wanted to get through this show - but they did not bail: the 2nd set is nearly 2hrs. No surprise that it's a below average show for '82 but there are still a few fine passages and two aces.
First Set. Shakedown starts to warm up by the jam. Bobby teases Promised Land but it's Beat it on Down the Line-13. I think the playing in Greatest Story is probably better than the sources (and even the FOH mix) indicate. They Love Each Other is energyless, but it's here that the SBD almost starts to settle and you can finally hear Phil, though Jer's guitar is still AUD-only. You need the AUDs for Mama Tried as well. The weather is really fucking with the sound by Big Railroad but Jer tries to add a bit more. Bobby teases See Rider Blues before deciding "I wanna do another one". A waiting Jer eventually predicts "play or die!" Jer again disappears from the SBD on Supplication. Seems the whole set was a saving-up for this Deal, which has more than enough spark to leave 'em happy for the break. The playing is wonderful considering the conditions, though a matrix would be nice.
Second Set. AUDs are still better for a Dewimmina that finally gets going by the end. The SBD for Althea has a different source but the rest of that SBD seems to have vanished. These are all average to below average versions until they bring out the energy at the end for those who did stay. As with others in the set, Jer winds up Let it Grow by the end. He's Gone has a longish jam but doesn't go anywhere. Truckin' has the now-cringe-worthy sex change lyric and is again messy until Jer pulls it into the jam section - though he soon walks off, followed by Brent. Bobby stays out and runs with it (a nice section for you Bobby rhythm heads). 1min of Drums is cut from the SBD. During Space Jer quickly bumps into a Spanish Jam theme and Bobby follows. When it breaks down Jer leads a theme on E-D-A that can't not go into NFA (some mistook this for a Stephen tease). Not Fade stays relatively unformed, then out of the deluge unexpectedly comes a really good Black Peter, with tight harmonies and Jer pathos. Like the first set, it seems as though it was all a saving-up for the encore with a stellar It's All Over Now Baby Blue (readjust pitch and balance).
1st Set:  C+
2nd Set: C
Overall = 2¾ stars
Highlights:
Deal - deluge in defiance
It's All Over, Baby Blue - leaves it all on stage for the remainders
SOURCES: The SBD has a frustrating mix, and the AUDs are more enjoyable for the majority. The best AUD is the Small_Donaldson_Ammons_Noel, which runs fast and needs -2% pitch correction. A matrix would fix many/most issues. The tunings are cut on almost all sources. For example, Weir's "This is the annual Red Rocks rain-out, but we're still here" before Althea is only on the Noel AUD and the mason_129707 AUD, and cut from all other AUDs and the SBD. All AUDS are pitched fast or slow. The browning-feinberg_32707 SBD runs fast on the 2nd set, needing -1% pitch, except for Althea.

despite what you may have heard - more times played in 1981 than in any other year, and 1983 is close behind

One of a very few 80's Spanish Jams. You almost get the feeling Jerry wanted to answer the jam that went into drums with something of his own.

Don't miss this one. A very nice board-- keyboards are a little bit high, but hey, so this show you really get to hear everything that Brent was doing. I'd actually like to see that for each band member sometimes--Bob and Phil are frequently mixed too low for my taste.
The show itself just totally smokes. I wasn't there, but sure wish I had been. I saw them three nights later in Austin which was plenty hot too--the summer 82 tour really was a truly outstanding tour-- one of the best Post-77 tours, if not the best.

I love this show. The recordings definitely capture the mood. However, there is not one recording which includes Weir's line, "Welcome to the annual Red Rocks Rainout..." between "Women are Smarter" and "Althea." I know he said it; I was there, and I have it on my Tour Diary.

Which night if at all?

I'm a big fan of early '80s AUDs, but I have to admit that this SBD source sounds much better than the best AUD source for this show. Listeners below have complained about Jerry's levels; I'm not sure that is that big of an issue. The AUD blasts Jerry but the rest of the band is drowned out, and the mics seem to be have a lot of space between them and the speakers despite being an FOB. Here, Bobby and Jerry are cranked, and the overall sound is much more clear.
Great show, competent non-CM SBD.

Good recording to play along to to since Jerry is almost non-existent in the mix.

If had to pick just one, the single best show I ever saw- out of close to 100 in total, from 1979-1992
Monster Shakedown to open, in the downpour...muffled by the sheets of water deluging us.
The L.S.D. jam to close the 1st set, zoooom! and there was real lightning in the sky.
Man Smart, Women Smarter was dance dance dance
A 2nd set Althea was intense, even the idea of it. LET IT GROW was melting to the roots
Surprise and delight that after the long pretty post "He's Gone" jam ( check garcia's wailing vocals too) there was yet another song- Truckin'
Thundering...on and on into the rising moon.
After Garcia left the stage, still more jamming- it went on and on, this set.Rhythm Devils, pounding on some tree log, at one point??
The Lost Spanish Bolero jam out of the space, sooo sooo soooooooo trippy. ( Only the x factor show at the Rocks in 1985 tops it for the mind melt level)
The thrill, then sadness at St Stephen not emerging was quickly forgotten in the monster NOT FADE AWAY. Garcia screaming the lyrics, and so true, our love affair with this band, and their's for us, would never fade.
Best Black Peter i ever heard live pure soul-unlike so many nights when it was perfunctory.
Perfect Sugar Magnolia. And sweet Baby Blue.
2nd night of the run, still had one more to go.
But first the post show afterglow at Chief Hosa campgrounds.
yup was about as 'high' as I ever got at a show, in terms of Lady Lucy~5x what i usually deployed~ hence melting glowing soaring, ah!

I loved this show. What a day. So many hours in the rain scoring a tix; amazingly transformed to a magical evening of crystal clear music.
